Observations of Solar Type II bursts at frequencies 10-30 MHz

International audience; We present the results of radio telescope UTR-2 observations of solar Type II radio bursts in the 10-30 MHz frequency range. These events possess a fine structure consisting of fast drift sub-bursts similar to Type III bursts. The frequency drift rate of the Type II bursts at decameter wavelengths is smaller than 0.1 MHz s-1. One of these bursts with herringbone structure has a wave-like backbone that almost does not drift. The features of the observed bursts are discussed.
